There are two types of coronary angiography: 1) coronary CTA under CT, the cost of coronary CTA is 1,382.6 yuan, and a bottle of contrast agent is needed, which costs 300-400 yuan. 2) coronary angiography under interventional catheter, the cost of these two examinations is different. If the coronary angiography under intervention is done, the cost of the test is more than 3000 yuan, this test requires hospitalization and will be combined with some other costs incurred. The choice of the appropriate angiography is based on the doctor’s request.
